Separate resealable mesh bag

Unique nitrate selective ion exchange resin which only removes nitrate! Even when the nitrate level is very low, no other substances which could lower the pH value (like calcium sulphate) are removed. This in comparison with other nitrate resins, which are known for years in the aquarium world. Operation: the nitrate ions are exchanged against harmless chloride ions. Particle size: 0,4 - 0,6 mm. Dosage: 1 liter resin can remove 30 GRAMS/liter nitrate. The resin can easily be regenerated with NaCl (200 grams of table salt per liter of resin) if the resin is saturated with nitrate. Application: fill a mesh bag with nitrate resin and then place the bag in the biological filter so that the water passes through it completely or put it in a separate filter house and let the water run through it in a by-pass with a flow of ± 5000 liters/hour. The lifespan of the resin is about 15 years but by means of organic pollution of the porous resin the actual lifespan will be around 5 years. The lifespan can be extended by regenerating the resin once a year in a hot saltwater solution (50°C).
